Research On Experiment Of Three-phase Flow Pipeline Transportation And Numeric Simulative Analysis

This thesis relied on channel round subsidy of Tianjin in "The research of wring the absorb type digs the mire ship to add gas to transport system to experiment". The main research of the digs the mire ship is the the resistance too big and the pipeline wear away Etc. The dig mire ship is used in Tidying up silt in the lake, Takeing the soil to reinforce the dam and Carrying on dredging to manage to the channel, Direct delivering the mud to appointed of the row mire orderd from the pipeline. The dig mire ship passes the row mire pipeline with solid-liquid two flow to transport mud. It shortage of the place is to lose the mire resistance greatly and transport distance shortly, high energy consume, block up easily,pipeline wears away easily etc, result in to dredge to cease work and safe trouble. Therefore, the research of the pipeline resistance that the mire ship have applied meaning of the theories research and engineering in the mire pipeline.Lose rubing and hindering and corroding the question and is influenced by many kinds of factors of the mud pipeline, usually main have relation on solid-liquid mutually of wall inside the causticity,tube the current velocity of the rough degree,pipeline shape,fluid with flow etc. This text comes from the experiment mutually of multiphase flow, The characteristic research of the fluid in the curved tube and spray mouth of the CFD in the dig the mire ship to lose the mire pipeline, carrying on study work as follows: Carry on the experiment design of the pipeline,the pipeline imitate experiment,data analysis and mechanism research;Build up a curved tube to flow a mathematics model according to the curved tube characteristic, According to curved tube and the spray mouth characteristic to build up flowing mathematics model, According to the fluid boundary condition to the current velocity of the fluid inside the analytical distribute of the pipeline , Distribute of the tube wall shears to slice dint, Distribute of the pressure , Distribute of the mutually , Study resistance with the blunt eclipse regulation of the pipeline, Find out resistance with blunt and the predominant factor of the eclipse condition of the pipeline Make use of the...
